According to the auction Web site, this version of the Apple computer is number 82 of those made, and was hand built by Steve Wozniak and then “despatched from the garage of Steve Jobs’ parents’ house – the return address on the original packaging present here.” (The Christie’s catalog uses a British spelling of dispatched. )

The version for sale through Christie’ths includes “the original packaging, manuals, cassette interface and basic tape, early documentation and provenance, and a commercially rare letter from Steve Jobs.”
